Hi all, could someone tell me which is the best user-friendly free/open source sql database system to use with R, particularly as a back-end for a data-hungry web page? Thanks in advance. Kind Regards Chibisi [[alternative HTML version deleted]]

Dear all, I am using lapply to generate plots by applying a plot function to a list of dataframes. e.g. lapply(dataSet, FUN = plotFunction) Is there a way to call the list item number inside the plot function so that I can identify each graph? Thanks Chibisi [[alternative HTML version deleted]]

Dear all, Does anyone know how to overlay a 3d line on a wireframe plot? I would also like to be able to keep the legend that you get when using the option: drape = TRUE when using the option: shade = TRUE. In addition, I would like to know how to keep the axes while getting rid of the box, I use this: par.box = list(col = NA) to get rid of the box but that also causes the axes to disappear.

Hi All, I would like to be able to use play3d() to translate the view along a surface, and zoom in and out. All the examples in play3d() function description are of rotations. I would also like to know if there is a method of creating a legend of for the 3d surface using rgl package. Thanks in advance. Chibisi [[alternative HTML version deleted]]

Hello R-users! I am trying to plot 3 vectors (x,y,z) of observations generated by mvrnorm in library(MASS). I tried plot3d in library(djmrgl) and scatterplot3d. But these program gives x,y,z axis which do not intersect at the origin (0,0,0). I searched through all the graphics related packages for R like xgobi, ggobi, grid and more. Quite confusing which one to choose. Would anyone recommend

Hi, anyone has experience with 3D plot (ex: in package RGL) I have a question, I draw a 3D plot of country, year and sales in z axis but when the type is "h" then it's ok but when I want to link the points and type is 'l' lines it's a mess Is there a way to link the points only in one direction? For example a unique line from each country through each year? The code

I have been using the ellipse function from the car package and the covariance matrix to draw an ellipse around a group of points to show the confidence limits. However, the points are actually represented by 3 variables so rather than plot each pairwise combination of variables in 2D I would like to plot the 'ellipse' in 3D using the djmrgl package. Can anyone offer advice on how I can

Dear all, I am trying to read a bunch of csv files using read.table() that are named "test_xxxxxx.csv" where "xxxxxx" has no particular pattern. Is there a way of reading all the files by specifying a truncated file name e.g. "test_" with some wild card characters, or would I have to laboriously create some vector with the "xxxxxx" names and iterate or

Hi I'm trying to make a 3d plot showing a point cloud, the corresponding data ellipse and the principal axes of the ellipse as vectors. library(rgl) data(trees) cov <- cov(trees) mu <- mean(trees) plot3d(trees, type="s", size=0.5, col="blue", cex=2) In this step, an extra box is added. I've tried using box=FALSE, but it has no effect. # how to avoid the

Dear all, I am trying to execute the simple example in snowfall http://cran.r-project.org/web/packages/snowfall/vignettes/snowfall.pdf ... require(snow) require(snowfall) sfInit( parallel=TRUE, cpus=2 ) sfLapply( 1:10, exp ) sfStop() I have installed the snow and snowfall packages in R on a machine with windows xp, however, after running the "sfInit( parallel=TRUE, cpus=2 )" line I

Dear all, I write to the community to know if other people expierenced the same problem. I want to save a rgl scene where I plotted a 3d cloud of spheres whose radius is set proportional to a given variable and coloured by another group variable and with 95% ellipsoids for distribution of any group. I had no problem at all for coding but I had two problem when saving the scene (in any format)

I have tried to install the drmrgl package and receive the following error: > library(djmrgl) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library 'D:/PROGRA~1/R/library/djmrgl/libs/djmrgl. dll': LoadLibrary failure: The specified procedure could not be found.

Dear users, I'm trying to produce a 3d bar plot but the x and y dimensions have categorical data -- so I only want 3 points on each axis. So I try: require(scatterplot3d) mymat<-data.frame( x=c(1,1,1,2,2,2,3,3,3), y=c(1,2,3,1,2,3,1,2,3), z=c(1,2,3,4,5,6,7,8,9)) scatterplot3d(mymat, type="h", lwd=5, pch=" ", xlab="xlabel",

Hello, I'm using the rgl package and plotting a plot with it. I'd like to have all the axes values auto-hide, but I want to plot a series of characters instead of the values of the measurement for 2 of the axes. So in the end I will have one axis (z actually) behave per normal (auto-hide) and I'd like the other two axes to be custom character vectors that auto-hide. Example: x <-

Hi, I am doing my way on R, with much experimenting. So, I am trying to plot a 3d graphic ussing "persp" and entering a data set (attached) of UTM coordinates as x,y and a pH values as z. However when I try an error message comes out telling that increasing x and y values are expected. Jus ordering the first vector does not help, and, of course, order the first two independently

Is it possible to do a graphic in 3D? This is my source: but this one is on 2D and at moment variables put on other variables, so it is difiicult to differentiate them visibly. plot(corresp(data,nf=2),xlim=c(-1,1),ylim=c(-1,1)); Thanks Sabine --------------------------------- ils, photos et vidéos !

Buenas tardes. ¿Sabe alguno de vosotros cómo indicar la variable con la que identificar los puntos con plot3d? library(rgl) plot3d(Data$RTLML,Data$JD,Data$SB) Las muestras pertenecen a una de dos categorías, según la variable "Family", pero no sé cómo hacer que me las represente de diferente color. Gracias, Manuel . -- Dr Manuel

Dear RGL experts, I haven't been able to add greek letters to my rgl plot3d. I have tried "expression" with no success. Here is the interested bit: > library(rgl) > cb <- cube3d() > plot3d(cb,xlab=expression(alpha),ylab="",zlab="",box=FALSE,alpha=0.5) The expression(alpha) appears as "alpha", rather than as a greek symbol. I suspect greek

Dear Users: I wish to save 3d scatter plots I have generated using the plot3d command in the rgl package. Any image format such as .tiff would work. Can anyone tell me how to do this? Thank you [[alternative HTML version deleted]]
